FAQ
What is the lug width of the Baume & Mercier Classima 10037?
The lug width of the Baume & Mercier Classima 10037 is 18mm. This measurement refers to the internal distance between the two spring bar attachment points on the case sides. You can verify this measurement using a digital caliper by measuring the distance between the metal lugs on the watch's flanks.
Which strap is best suited for the Classima 10037 in rose gold?
For the Classima 10037 in rose gold, genuine alligator is the most refined choice: its regular grain and developing patina over time create a perfect dialogue with the watch's lustre. Alternatively, vegetable-tanned Italian calf (cognac or tobacco tones) amplifies the warmth of the timepiece, whilst shell cordovan offers natural thickness and intrinsic sheen that elegantly complements the case material.
How do you change the strap on a Baume & Mercier watch?
Changing the strap on a Baume & Mercier Classima 10037 involves removing the spring bars (small metal levers on the watch's flanks). Use a spring bar removal tool to gently lever out the spring bars and extract them from the case. Once removed, the old strap separates from the case. Insert the new strap by threading the spring bars into the corresponding holes and pressing firmly until they click into place. If you prefer to avoid any risk of scratching, have a professional assist you.
Is an aftermarket strap compatible with the Classima 10037?
Yes, any strap with an 18mm lug width is compatible with the Classima 10037. Milano Straps offers a wide selection of handcrafted 18mm straps, customisable for length, colour, initials, and stitching thread type. Ensure that the new strap has properly dimensioned spring bars to avoid damaging the case during installation.
How long does a leather strap last on a luxury watch?
Durability depends on the material and usage patterns. A high-quality artisanal alligator or shell cordovan strap, such as those from Milano Straps, can last 5-10 years with moderate daily wear. Vegetable-tanned calf tends to age more quickly (3-7 years) but develops a beautiful patina. Factors including perspiration, sun exposure, and frequent water exposure shorten strap lifespan. Proper maintenance—periodic leather hydration and drying after water contact—significantly extends strap longevity.
